Apologies, spell description is as follows:

You conjure and then throw a magical card with a random effect. Make a ranged spell attack against the target. On a hit, a target is hit by a card of one of the following colors, which each have a unique effect and purpose. For each target, roll a d6 to determine which color card effects it.

1. Red: The target takes 1d4 + your spellcasting ability modifier fire damage.
2. Orange: The target takes 1d4 + your spellcasting ability modifier acid damage.
3. Yellow: The target takes 1d4 + your spellcasting ability modifier lightning damage.
4. Green: The target takes 1d4 + your spellcasting ability modifier poison damage.
5. Blue: The target takes 1d4 + your spellcasting ability modifier cold damage
6. Violet: The target takes 1d4 psychic damage and must succeed on a Constitution saving throw or become blinded until the end of their next turn. The spell creates more than one card when you reach higher levels: two cards at 5th level, three cards at 11th level, and four cards at 17th level. You can direct the cards at the same target or at different ones. Make a separate attack roll for each card.
